The LNCS journal Transactions on Aspect-Oriented Software Development is devoted to all facets of aspect-oriented software development (AOSD) techniques in the context of all phases of the software life cycle, from requirements and design to implementation, maintenance and evolution. The focus of the journal is on approaches for systematic identification, modularization, representation and composition of crosscutting concerns, i.e., the aspects and evaluation of such approaches and their impact on improving quality attributes of software systems. This volume, the 10th in the Transactions on Aspect-Oriented Software Development series, contains revised, extended versions of the top five papers presented at AOSD 2012. The topics covered include debugging, analysis of software product lines, distributed software architectures, and empirical study of language support for software evolution.

Taking into account more than one aspect can be a little harder, but many large scale successful projects in industry provide some evidence that engineers know how di?erent concerns should be handled. The real challenge is reducing the e?ort that the engineerhasto expendwhengrapplingwithmanyinter-dependentconcerns.For example, in a product-line context, when an engineer wants to replace a variant of an aspect used in a system, she should be able to do this cheaply, quickly and safely. Manually weaving every aspect is not an option. Unlike many models used in the sciences, models in software and in lingu- tics have the same nature as the things they model. In software, this provides an opportunity to automatically derive software from its model, that is, to - tomate the weaving process. This requires models to be formal, and the weaving process be described as a program (i.e., an executable meta-model) manipul- ing models to produce a detailed design. The detailed design produced by the weaving process can ultimately be transformed to code or at least test suites.

This volume presents two regular revised papers, a guest editors' introduction, and six papers in a special section that have been through a careful peer reviewing process by the journal's Editorial Board. Besides a wide range of topics from software design to implementation of aspect-oriented languages, the six papers of the special section concentrate on AOP systems, software and middleware.

This volume, the 9th in the Transactions on Aspect-Oriented Software Development series, contains three regular submissions and two special sections, each consisting of two papers. The papers focus on the following topics: modularization, pointcut language, dynamic adaptation, event-based programming, aspect-aware design, system software, object composition and templates.

This volume, the 11th in the Transactions on Aspect-Oriented Software Development series, consists of two parts. The first part focuses on runtime verification and analysis, highlighting runtime verification as a "killer" application of aspect-orientation. The second part contains revised and extended versions of the five best papers submitted to Modularity:aosd 2013, presenting current research related to modularity and covering topics such as formal methods and type systems, static analysis approaches for software architectures, model-driven engineering and model composition, aspect-oriented programming, event-driven programming and reactive programming.

This volume, the 12th in the Transactions on Aspect-Oriented Software Development series, contains one regular paper, on modular reasoning in aspect-oriented languages from a substitution perspective, and four extended, improved papers selected from those presented at Modularity 2014. Topics covered include novel dynamic semantics through delegation proxies, modularity potential detection based on co-change clusters, improvements in reusability for components of semantic specifications of programming languages, and probabilistic model checking applied to dynamically generated members of a product line.

This volume, the 8th in the Transactions on Aspect-Oriented Software Development series, contains two regular submissions and a special section, consisting of five papers, on the industrial applications of aspect technology. The regular papers describe a framework for constructing aspect weavers, and patterns for reusable aspects. The special section begins with an invited contribution on how AspectJ is making its way from an exciting new hype topic to a valuable technology in enterprise computing. The remaining four papers each cover different industrial applications of aspect technology, which include a telecommunication platform, a framework for embedding user assistance in independently developed applications, a platform for digital publishing, and a framework for program code analysis and manipulation.

– Those who want to learn about AOM ?nd in this special issue a concise collection of descriptions of solid and mature AOM approaches. They only have to take the time to understand one case study in order to appreciate the sample models shown in all papers. – Those who want to apply AOM for a particular purpose and are looking for the most appropriate AOM technique can use the papers presented in this specialissue to identify the mostpromisingapproach(es).By identifying similarities between their problem and the case study they should be able to determine candidate AOM approaches easily. – Those working on their own AOM approach can readily identify approaches that were able to handle concerns that their own approach is not able to handle elegantly. This stimulates cross-fertilization between approaches and collaborative research. – Thoseengineering researchersthat areworkingon enhancing softwaredev- opment processes can use the example models presented in this special issue to understand the potential bene?ts of using AOM techniques at di?erent phases of the software development life-cycle.
